Using Aperture 3 on my iMac. I have thousands of pictures. Right now they are ALL in 1 library. I'm concerned about putting "all my eggs in 1 basket". If the library gets corrupted, etc... I could lose everything right? And it can also start slowing down over time. I just came back from a trip and took 7gb of pictures. Should I create a new library for vacations only, or library2, etc...? What are your suggestions to make sure I don't jeopardize the integrity of my library/pics and have A3 as fast as possible? Any suggestions appreciated. Also, if you want, tell me how you organize all your pics, if you have many.
